Direction: It consists of two statements, one labeled as ‘Statement (I)’ and the others as ‘Statement (II)’. You are to examine these two statements carefully and select the answer using the codes given below:Statement (I): In an ac dynamometer-type wattmeter the instantaneous value of developed deflecting torque is proportional to the product of voltage and current in the respective coils at the corresponding instant, the constant of proportionality is the same as in the case of dc use.Statement (II): The moving system of the meter is prevented by its Inertia from following the variations in the deflecting torque which takes place during each cycle, and takes up a position corresponding to the average value of the torque.
